ASSIGNOR 1'0 UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY DEVICE roe USE IN COVERING HEELS Application filed 'March 30, 1928, Serial No.

This inventionrelates to devices for use in covering unattached heels for boots and shoes; with leather, fabric or other sheetrmateriah It is shown herein as embodied in ajack for 5 supporting a heel in convenient position for applying the cover thereto and for guiding the heel into the positions most favorable. for the operator in conformingthe cover to the surface of the heel. i

In covering a heel, it is convenient to sup port it initially in an elevated position with its breast down and in this position the cover may be most easily wrapped about the rear curved surface of the heel and adjusted for a uniform margin of overlap; In conforming the covering material to the surface of the heel, it is the practice to work bothways from the rear median line of the heel; To facili-.

tate this procedure, it is proposed to provide heel sustaining means mounted for movement about a horizontal axis so that the heel may be swung downwardly on either side from its initial position, presenting its side faces successively in position where the operator may inspect and work upon them to the best advantage.

In accordance with an important feature of the invention, the supporting means for the heel is so costructed and arranged that, as theheel is swungabout a longitud nal axis in the 1 manner indicated, it is also turned about a transverse axis and its rear curved face turned toward the operator, facing always 111 the same direction upon whichever side the. heel may be swung. In apreferred construc tion for accomplishing this result, the heel supporting means is mounted for movement about two axes at right angles toeach other:

and provision is made for constrainingthe the heel simultaneously about these two axes. Preferably, and as herein shown, theh'eel supporting mechanism is so constructedand organized thatthe heel may be moved in the desired predetermined manner by the appliof p tor in workingthe cover over the surface of the heel.

supporting means for bodily movement with aeaoca'and in Great Britain May 17,1927.-

means for holding the covering upon the heel to preventslipping and'to facilitate the operation of conforming the cover to the surface of the heel. These comprise two instrumen- 'talities which are each useful singly but which are preferably employed together, thus presenting an additional and cooperative benefit. .As herein shown, the first of these mstrumentalities comprises a band constructed and arranged to be tensionecl about the back of the heel after the cover has been presented thereto to prevent slipping of the latter. and being connected to a lever by which it may. be coveniently tensioned and locked. Preferably, forsustaining the heel against the pull of the tension of theband.

The. second instrumentality comprises means for gripping the margin of the 'covermg ata point adjacent to the heel-seat edge of the heel, for the purpose of positively hold in g a part of while the. remainder is conformed by the hands of the heel. In this connection, another feature of the invention consists in cover gripping members, disposed in separated or inoperative position while the heel-is supported in it initial position but beingtmovable automatically to engage the margin of the cover when the heel is moved in either directionfrom its initial position. 7 I i i These and otherfeatures of the invention will be best understood and appreciated from the following description of a preferred enibodiment thereof, selected for'purposes of illustration and shown in the accompanying drawings, in which .Fig. 1 is a'plan View of the device,'with the parts in, position for sustaining a heel swung downwardly into its left hand position; and f Fig.y2 is'aview of the device in side ele-' gablOIl, showing the heel in its initial posi- 1011. l I l The device comprisesa base plate 2, having an adjustable support is provided operator to the surfaces of the the cover in the proper position an upstanding integ'ralcollar-3 which forms H c l ofahea'd 5: .The head 5' is bored to form Other features of the invention relate to Ion accommodate heels of varying height. might also be usedfor swinging the 10 for fengagingor disengaging the heel but, "as a general thing," would be tooslow for operating with the arm or aw 8 and pivotally mounted upon a pin 9 extending be-.

tween cars which form a part of thebracket member 7 is a lever 10, the upper end of which is shaped to engage the tread face of the heel and provided with a prongor tooth for that purpose. The lower. endof the lever 10 is formed toreceive transverse trunnions 11 which project from aunt-12 threaded upon a horizontal bar 13, which is located at the axisflof. the bracket member 7 in a bore formed 'in the. stem. 6 for that purpose. The bar 13' extends entirely through the stem 6 and is provided at its outer .end with a hand. wheel let, by which-the bar may besturned to shift the nut- 12 and swing the lever 10 toward or away from the arm 8.

The bar l3 iszmounted to rotate in thestem 6 when the hand wheel 1.4 is turnedand it is also free for longitudinal movement toward the right, as viewed in Fig. 2", although it is constantly urged toward the left by a compression spring 17 seated in. a recess in the stem Gsurrounding the bar 13,. bearing at one end against a shoulder in the stern and at the other against a shoulder .on the bar 13 so as to urge the bar always toward the left, maintaining the end of the hub of the hand wheel 14; against the end of. the

* stem .6. The stem 6 is free to rotate in its horizontal bearing but is retained against longitudinal movement by a transverse pin 18, set in the head 5 and engaging a circunv ferential groove in the stem 6. v i

The handwheel la-may be turned to adjust the position ofv this purpose. In order to -open" the jaws rapidly and fully when it is desired to place a heel in position,

are provided :for shifting the bar 13 longi this end, a bell crank. lever" is pivotally" treadle-operated means tudina'lly in opposition to the spring 17?. To

.of the. operator, it

22- of as bell in the bearings of the head 5. These parts are interconnected in such a manner that these movements-take place simultaneously or, in other words, when the bracket member 7 is moved about its horizontal axis, this axis is bodily shifted about the vertical axis ed to the heel supported by the bracket member '7. This result is secured by two intermeshingbevel gears, one gear 26 of which is secured to. the collar 3, the other gear 27 being secured to the stem 6. It will be. apparent that when the bracket member is swung in either direction, the action of thegears 26 and 27 will cause the stem. 4 to turn with the head5 in one direction or the other.

The initial position ofv the bracket 7 is determined by a spring-pressed plunger 30, mounted in the bracket member and having a pointed lower end foren'gaging a taper recess inthe surface of the head'5. When theplunger 30 is so engaged, the bracketmember 7 supportsthe' heel above-it in the i3? elevated position shownin Fig.2. In this facing the right-hand. side of the device, as

shown in Fig.2.

Following such initial application'of the cover, itis desirable to position'theheel first with oneside and then with the other side uppermost, as hasbeen indicated. The heel may be pushed downwardly on either side by the: operator until it occupies-some such position asfshown in Fig. 1, further motion being limited by the engagement of the bracket member withone or the other of a If pair of transversely extending lugs 32 upon the head 5. In this movement of the heel about thelongitudinal horizontal: axis of the bracket member 7,-the heel isalso turned about the transverse or vertical axis of the 1 head by so that it is broughtnearer the oper ator and disposed with its rear surface to In Fig. 1, the heel is indicated in the position it would occupy' if swung down uponthe left-hand of the op erator. If swung down upon the right-hand would occupy a symmetrieally disposed position with its other side uppermost upon the othersideof'the device andwith its rear-"curved surface: still toward the operator; i f I v The instrumentality for preventing any I shiftingof 'thecover upon theheel? once it has been placed incontact with the rear surp face thereof comprises arband orstirrup'33 of leather vor similar materialipivot'ed at both ends to a lever. 3'4 which, in turn, is pivoted" at 35 to'the base 'of the arm f the bracket .7 V

Prior to the application of the cover, the lever 34 is swung upwardly and the stirrup 3'3 slipped forwardly out of the way of the" heel-retaining jaws. This stirrup notonly holds the cover against slipping upon the heel but prevents any tendency thereof to lift from the concave portion of the rear and the sides of the heel without-covering sufficient surface to interfere with the further application of the cover.

In order to sustain the heel against the pull of the band 33 and prevent any tendency toward displacement in the heel-hold ing jaws, an adjustable support 45 is proa'curved outer face for enbreast surface of the heel. It is justment and frictionally maintained in whatever position it may be set. The direction of pull of the band 33 is substantially across the pivot point of the support 45, so that there is no tendency to displace this member in operation.

The second instrumentality for retaining the cover in place comprises a stationary jaw 40 which is mounted upon the arm 8 of the bracket able jaw 41, carried by a rod 42 mounted to move longitudinally in a boreformed in a boss 44 on the arm 8 and moved down or inwardly at all times by a compression spring 46 extending bet-ween the lower end of the boss 44 and the rod 42. A cam while the bracket member 7 occupies its initial position. This arrangement permits the application of the cover to the heel and the insertion of its margin adjacent to the rear edge of the heel-seat surface of the heel between the cover gripping jaws. As soon asposition,

the heel is swung out of its initial the end-of the rod 42 surface 43 and the cover positively, holding a portion of the cover in and preventing any shifting thereof toward'the tread of the heel.

The operation of the device will be apparent from the foregoing descriptionv but may be briefly summarized as follows. Having the heel jaws to accommodate the type of covered, the operator depresses the treadle rod and presents a'heel between the jaws passes oil" the. cam

gripping is released, the action of theisp'ring 17 causes member and cooperates with amov enlarged convex end of the surface .43, projecting from the head 5, is arranged to elevatetherod 42 and holdthe cover gripping jaws open;

the support 45 adjusted and the band 33 ten-- sioned by depressing the lever 34. As the operator works swings the heel gradually bringing more and more of the right-hand surface uppermost and maintaining the rear surface of the heel toward him. en the conforming operation has pr0 ceeded to the breast edge of the'heel, the

eel is swung in the through its initial position and down upon the right-hand side of the operator. The

action of the cover gripping jaws takes place and constrained for bodily movement with the heel simultaneously about two axes disposed at an angle to each other.
